Abstract
The paper reports the data on the synthesis of a new, previously not described, series of oligodiuretancarbofunctional alcohols based on aliphatic individual or oligomeric diols and polyisocyanate at the following ratio: one gram-equivalent of polyisocyanate per one mole of the corresponding diol. The isolated compounds are transparent, homogeneous, slightly colored dark-colored substances, some of which crystallize under room conditions, and the other part is a very viscous and sticky liquid. Their physicochemical constants are given (nD20, wt.% of –OH groups, wt.% of the latter –NCO groups, and urethane group content). Such oligodiuretan-containing carbofunctional alcohols are well soluble in ketones, esters, ethers, chlorine-containing and aromatic hydrocarbons, and aprotic solvents. They are poorly and even insoluble in non-polar hydrocarbons (hexane, heptane, etc.). Their structure is confirmed by functional analysis and IR spectra.
